The money was picked up by their Loomis intentional truck to deliver to the Bank of Ireland.

Jurors learned they picked up the money from the BA cargo depot at around 8.30am with Siddique driving the armoured van and Singh the security guard.

Shortly after leaving the depot, Singh went to the toilet, but when he came out Siddique had driven off with the £7million in cash.

Instead of raising the alarm Singh waited for 20 minutes, smoked a cigarette, before telling colleagues in another van what had happened.

In the meantime it is alleged the cash was being transferred from the Loomis security van into a second vehicle parked in a quiet secluded road in Feltham, west London.

The jury were told the pair, along with others, allegedly staged the heist on the van.

Siddique was found a few hours later tied up in a remote area near Gerrard's Cross.

Prosecutor Sandip Singh QC said: "It was an audacious theft carefully planned and executed and you may think it would make a Hollywood movie script, they would call it the 'Heathrow Heist' if anyone wanted to write a script about it."

"It is one of the biggest in British criminal history, there have been bigger, but £7million in a significant amount.

"It was also an inside job, to use the colloquialism, and we say it had to be and inside job by these two defendants.

"They acted out their parts to the scripts they had already agreed."
